Abstract (en)
[origin: EP1384650A2] The terminal voltages of respective phase coils of a steering shaft driving motor (6) constituted by a three-phase brushless motor are separately detected. When the terminal voltages detected at at least three different conducting terminals u, v, and w are made Vu, Vv, and Vw, respectively, and the values when those detected values Vu, Vv, and Vw are arranged in order from largest to smallest voltage are made V1, V2, and V3, respectively, provided that V1≥V2≥V3, a calculation is performed to determine if V1 + V3 coincides with 2*V2 within a predetermined allowable range, and a failure is determined based on results obtained from such a calculation. <IMAGE>
